TRIDELTA offers a broad portfolio on surge arresters for the application on high voltage up to 800 kV with the reliable SB series with porcelain housing and with the series SBK, SBKC and SBKT three designs with silicone housing.

Overview

Surge arresters for High Voltage applications up to 800 kV, SB series with porcelain housing, series SBK, SBKC and SBKT – three designs with silicone housing

Porcelain

Surge arresters in top quality porcelain housings up to 800 kV, with outstanding sealing design for longest service life, available in 3 construction designs

Silicone - Solid Core Design

Surge arresters with silicone housing up to 170 kV, economic and very low weight, very convenient for application as station or transmission line surge arresters

Silicone - Cage Design

Surge arresters with silicone housing up to 420 kV for applications with advanced mechanical requirements, best price/performance ratio, use as station or transmission line surge arresters

Silicone - Tube Design

Surge arresters with silicone housing as a tube design that provides highest mechanical resistance and excellent tightness, up to 800 kV, use as station surge arrester, especially suitable for very severe seismic conditions

Medium Voltage Metal Oxide Surge Arresters and Limiters up to 51 kV

Tridelta has a long tradition in the production of distribution arresters. Our first medium voltage arresters were produced in 1962.The housing of these valve-type arresters was generally porcelain. Since 1996 our medium voltage arrester are made only using light and cost-effective silicone housing; they have passed the 5000h ageing test successfully.

Outdoor Applications

MV surge arresters with silicone housing – customized solutions available through a wide range of creepage distance, fixation means, terminals and accessories

Indoor Applications

MV surge arresters for protection of power transformers, metalclad switchgears and cable terminations in indoor environments – available with different possibilities of terminals and customized length adaptation

DC Arresters and Transmission Line Arresters

TRIDELTA offers surge arresters up to 4,8 kV DC for rolling stock, tram or streetcars or for protection of DC equipment and overhead lines. Line arresters are an effective and economical option to protect existing as well as new transmission lines against lightning overvoltages in order to increase grid reliability and availability of transmission lines. Line arresters are suitable especially for line sections with low earthing impedance of the line towers, areas with high lightning activity, transmission lines without shield wire protection and for transmission lines with very high demand to their availability.

DC Arresters

Surge arresters up to 4,8 kV DC for rolling stock, tram, or streetcars or for protection of DC equipment and overhead lines

Transmission Line Arresters

Effective Protection of overhead lines from lightning overvoltage to improve line availability and stability of the electrical grid. Design as NGLA-Types (Non Gapped Line Arresters) with silicone housing

Monitoring

Monitoring solutions for surge arresters for early detection of failures modes
